A federal grand jury has added a new charge against a Kentucky sheriff's deputy, this one related to an alleged assault in 2008.

The grand jury in Louisville says 48-year-old Steven Molen attacked a person identified only as "C.F.' in Russell County on Aug. 24, 2008 and caused bodily injury. The new charge was unsealed Thursday.

Molen, a Pulaski County Deputy, had previously been charged in Lexington with two other counts of violating the civil rights of different victims by using excessive force in 2009 and 2011.

Molen entered a not guilty plea to the charges in Lexington in July. A trial in that case is scheduled for December.
